Compatibility issue between IE and AOL

Hello,
I am having issues in my computer. I am using a Windows Vista machine.
My problem is, my Internet Explorer does not work with AOL. Even if I am not logged in at AOL, and even if I will exit AOL from the system tray. I am thinking there’s a conflict between the two.
However, I do not want to give up any of those. I tried using other browser, but I still liked Internet Explorer more than anything else. It works faster in all my favorite web pages that I am visiting unlike Mozilla and Netscape.
Are there any more options to make them both work at the same time?
